San Francisco, city of « tech » and … dung. This is what prompted a developer to create the SnapCrap app, to photograph dog and human excrement on public roads and ask in real time the passage of the road.

Once the object of the crime has been photographed, the app – very basic – automatically geolocates it, offers humorous legends and sends it to the municipal services, 311. Famous for its many technology companies, San Francisco is also known for the filth of some neighborhoods, a problem largely attributed to the thousands of homeless people who live there and have no choice but to relieve themselves on public roads.

According to the San Francisco Chronicle, the 311 receives 65 calls per day from residents reporting dung to be cleaned. The city, which considers that it has become one of its main problems, has even decided to launch a « Poop Patrol » (« Poop Brigade »). Comprised of five employees, it’s responsible for cleaning the neighborhood of Tenderloin, particularly affected by this phenomenon and which houses nearly half of the homeless in the city.
